Any type of heat whether it be wood gas or electric, comes with combustion "flash" hazards - it says so right on the UL label. The way I see it, a gas appliance that uses HSI (hot surface ignition) is more likely to flash on external combustibles then one that uses a pilot light. These HSI units are totally cold before they get a run command to heat the igniter, where a pilot requires more combustion air and will scavenge small amounts of vapor and "wick off" on smaller concentrations. A little phoomp is better then a big bang anyday.. Wood heat is probably better at scavenging flammable fumes before they reach the big-bang level of concentration then any of them. The trick is, is to not let concentration reach BANG LEVEL.

Do a good sniff around before you wick that stove!

Another thing too.. I still wonder how many of my brain cells got wasted to that old propane dish. Working on the hotrod used to be a GAS, litterally..

here in canada eh, we are not allowed to use an unvented propane heater indoors. the place i worked imported them(not knowing the laws)for resale. when they ran the ad, we were contacted by the powers that be, and told we could not even sell them, we finally cleared them out calling them greenhouse heaters.
there is so much moisture released as a by-product of the burn, i could not see them as good for any piece of metal, let alone a valueable hot rod. mike

Ventless heaters should be used for short periods of time, many are 99 0/0 efficient but still put carbon monoxide into the area it is heating. If the area is not real airtight, it has a way of fumes to escape, through a vent in the roof or something along that line, it may not be too bad. A carbon monoxide detector might be a smart investment. A quick way to take the chill off a room, I would be leery of using them for the main heat source. Kevin, the reason your flame is turning yellow is it is pulling more air to the burner. Blue flames are the hottest, yellow is getting more oxygen, orange will burn with less heat and be a dirtier burn, putting more smoke and particulates into the system. Dan

In my shop here at the house I used a electric heat pump out of a trailer house, heat and air. Works great and it was free.

Earl... I have a ventless propane in my garage. Works great....Except it puts a great deal of moisture in the air. Windows are steamed up all the time when it is cold out. AND if the compressor kicks on, or you start grinding, etc. the thing will start burning yellow instead of a clean blue. In my opinion, shop around for a regular furnace to heat with. A good source would be where they sell mobile homes. I had our furnace replaced this year and kept the older one (12 years old) for use in the garage. My recomendation would be to not put in a ventless. Also search down thru the threads in the Garage forum. One member put in the type that hangs from the ceiling.

Garage Heat

I'm finishing up a 30x42 garage/shop and am considering using one or two ventless, wall mounted natural gas heaters. Anybody got experience with these? Is it dangerous to mount these in an area where flammables are present? There is no pilot - they ignite with a piezo? button--like a gas grill.
Also, I'm trying to decide how to finish the 12' ceiling. 1/4"OSB? Drywall? or?

I 've got 6" of fiberglass everywhere I can, foam in the doors and a good ceiling fan. I use a cast iron wood stove for heat. I'd really prefer to have a mobile home oil furnace or waste oil furnace for quicker response-you can't just run out for 1/2 an hour's work- but I tore down a two story log cabin that was next to the shop when I rebuilt it, so I have a lifetime supply of free firewood right on site. It's nice heat one you get it going.

heat?

A large wood furnace but I didn't buy any wood this year. I have priced some wood recently but still haven't bought any?? Would rather play inside or read, or go to the club, but it is my hobby work space so maybe I needed a break??

I just got through insulating, sheetrocking 5/8" and installed a natural gas unit.

I have a brand new Trane gas furnace sitting in my garage waiting for me to run a gas line from the house. Itís been too darn cold (30 degrees is COLD here) to mess with it! LOL!

Seriously though, Iím waiting on a friend to bring his trench digger so I can run a gas line. I also plan to run new cable tv line, CAT 5 for Internet, new phone line, water, and 220 service. More than one trench I recon.
